9.17.1 Basic operation
1. Rapid movement to the center of the hole (X, Y).
2. Rapid movement to the reference plane (Z).
3. Rapid movement of the plane axes to the thread entry point (it only makes this movement if
parameter E has been programmed).
4. Rapid movement to the thread entry point coordinate along the longitudinal axis.
5. Thread entry with a helical movement tangent to the first helical threading path.
6. Making the thread according to the value of parameter C.
 If C=0:
·1· Helical movement, in the direction indicated in parameter J, to the bottom of the thread
(the movement will only be one revolution).
·2· Helical thread exiting movement, tangent to the previous helical path. If parameter E has
not been programmed, the exit point will correspond with the coordinates of the hole
center.
It must be borne in mind that in the exit tangent to the helical path, the exit point will exceed
the coordinate of the bottom of the thread along the longitudinal axis.
 If C=1:
·1· Helical movement, with the pitch and direction given in parameter J, to the bottom of the
thread.
·2· Helical thread exiting movement, tangent to the previous helical path. If parameter E has
not been programmed, the exit point will correspond with the coordinates of the hole
center.
It must be borne in mind that in the exit tangent to the helical path, the exit point will exceed
the coordinate of the bottom of the thread along the longitudinal axis.
 If C=n:
·1· Helical movement, with the pitch and direction given in parameter J, (the movement will
be one revolution).
·2· Helical thread exiting movement, tangent to the previous helical path. If parameter E has
not been programmed, the exit point will correspond with the coordinates of the hole
center.
·3· Rapid movement to the thread entry point of the next threading path.
·4· Rapid movement to the Z coordinate of the thread entry point of the next threading path.
·5· Repetition of the previous 3 steps until reaching the bottom of the thread. It must be borne
in mind that in the last helical exit, the exit point will exceed the coordinate of the bottom
of the thread along the longitudinal axis.
7. Rapid movement to the center of the hole (X, Y).
8. Rapid movement to the thread entry coordinate along the longitudinal axis.
9. Repetition of steps 3 to 8 until reaching the depth of the finishing stock.
10.Repetition of steps 3 to 8 until reaching the bottom of the thread.
11.Rapid movement to the reference plane (G99) or to the starting plane (G98).
